On 24 Nov, 2015, Sameer Agarwal, Software Engineer at Databricks, gave us an introduction of BlinkDB in the MeetUp organized by Knoldus. It was a great session. We are thankful to Sameer. It was quite inspiring and appreciated by all attendees.

BlinkDB is a massively parallel, approximate query engine for running interactive SQL queries on large volumes of data. It allows users to trade-off query accuracy for response time, enabling interactive queries over massive data by running queries on data samples and presenting results annotated with meaningful error bars.
